摘要
A method for determining an amount of a fissile element in a nuclear fuel assembly (FA), the method comprising: irradiating a given FA with a first beam of gamma radiation of known intensity and known spectrum; determining a first attenuated intensity equal to intensity of the gamma radiation from the first beam which passes through the given FA; and using the determined first attenuated intensity to determine an amount of the fissile element in the given FA and/or a bumup credit for the FA.
